Tony Robbins wealth strategy: save $300 per month from age 20 to age 30 (i.e. 10 years), and then you stop making any monthly deposits, and you leave the account alone until you are 65 years old (i.e. leave it alone for 35 years).

1) if you make monthly payments of $300 for a time period of 10 years, what was the total amount you invested (not the FV, just the total amount you deposited)?

Answer: $36,000
